sidebars for blog page and blog post

I get very confused with which widgets get displayed. I would like to create a sidebar for posts only with almost the same elements that are in the Displayed Everywhere widget. BUT I do not want it showing on the blog page itself. For that page I created custom sidebar widget. Now the blog page shows my custom sidebar along with the Displayed Everywhere sidebar.
The posts will be added by the client so I want it as automatic as possible. so how do I create a sidebar that will display on all posts but NOT on the blog page?

For the blog page I set the side bar to the following layout:
Sidebar settings- Select desired page layout >Right sidebar
Sidebar setting – Choose a custom sidebar for this entry>blog PAGE sidebar (that is my custom widget area)
ALSO, for the blog page, I would like a tutorial on configuring the blog post element… I am not familiar with all the options there. Also interested in custom blog page.
